Never used VLD's but used a .300Win a lot.
In my rifle the OAL that just touches the lands is always too long to function properly through the magazine. I have hunting loads that are actually longer than the maximum OAL in the manuals, but which testing proves function well through the magazine, and I have my super-accurate-tack-driving-money-winning loads that I must single load if I am at the range playing games.
I physically measure the maximum OAL for each bullet I use for the specific rifle I have, and then make adjustments to get the relief from the lands that I need for reliable functioning and/or best accuracy.
I know I'm ignoring the specs in the manuals, but I believe I'm doing it safely. The industry specifications are there to make any round that conforms to spec. function properly in any gun that conforms. The main advantage of reloading is that you can make specific rounds conform to your specific guns.
